What do you mean "to low of a stock ride height?"  It is perfect!
And the cowl tag is clear as a bell!

 I had the same problem. In my case the clutch fork bearing retainer was not riveted on the fork correctly. It was not letting the bearing center itself over the tranny output shaft, adding a lot of side pressure. As I worked the clutch during driving the bearing would really heat up. When I tore it down to find the problem the bearing was ready to fall apart from wear.
Not sure of the brand of fork but it was after market so there are more out there!

Hey Jimmy V. if you happen to do a compression test or vacuum ck. I would love to know what #s you get. I have those rockers and I only have 7.5 inches of vacuum. I would like to eliminate them being the culprit. Everything else has been done! Thanks, Gary (myty)

 Steve is correct on the very close mating with a car.

Engine casting date, build date (Production date), and installed in car just days away.

 Todd, that is good info on that felpro gasket #. The last 2 gaskets seemed to sit to low on the intake openings which worsened my chances for a good seal with that imperfect intake angle.  Thanks again, Gary. I will let u know!

 Although it may seem unrelated, my z starts hard, runs very rough and spits and sputters for the first several minutes of warm up. Been thru several carbs and now have the  original back on after having it restored with slightly larger primary jets and squirters. After removing the intake we found the intake runners soaked with oil and found where the surfaces mate with the head weren't right (to tight at the bottom as compared with the top edge). Still sucking oil but better as my vacuum is up to a mere 7.5 ".
 Well it seems the manifold has been over worked so I just received another 472 in great shape to try. When I do this I will ck. the head angles to see if someone angle  milled them  like they used to
 Any way, thru the constant pondering we checked the cyl compression and I thought it to be low.
Bottom line... Low vacuum, sucking oil and starts very hard maybe because of oil on the plugs?
This car just finished a frame off resto. We changed the cam out and degreed thinking it was  the vac, issue
  Thanks Gary

 I have seen that 190 psi figure too but it just seem s that a short stroker with a huge duration cam and lots of "bleed off" could develop such high Numbers. The only thing that is not stock are the pro magnum rockers. I guess I'll try some stock rockers next. Hasn't someone out there ever done a compression test on a 302?  Thanks, Gary

 Oh yea, and the leak down test was good. Any one?

Ok guys, has anyone done a compression test on a dz302?  Mine average 125 to 130 after 3 turns of the motor and 150 to 155 after maxing out at 7 turns.  Is this in the ball park or a little low?  All plugs removed, throttle open, 11 to 1 pistons, comp 346 cam, rebuilt w new rings and broken in. Jerry, you there?  Thank you, Gary
